Mark works as a Network Administrator for NetTech Inc. He wants users to access only those resources that are required for them. Which of the following access control models will he use? Response:

Mandatory Access Control (MAC) is a highly restrictive model based on security labels and clearances, which is not typically used for common organizational least privilege enforcement.

Role-Based Access Control (RBAC) assigns permissions based on an individual's role within an organization, ensuring users only have access to resources required for their specific job functions.

Discretionary Access Control (DAC) allows resource owners to grant or deny access, which can lead to inconsistent security policies and does not easily enforce organization-wide least privilege.

Policy Access Control is a general concept for governing access, not a specific access control model like RBAC, MAC, or DAC.
